One of the nice things about using RPM is that the packages you manage don't end up going into some kind of black hole. Nothing would be worse than to install, upgrade, and erase several different packages and not have a clue as to what's on your system. In fact, RPM's query function can help you get out of sticky situations like: * You're poking around your system, and you come across a file that you just can't identify. Where did it come from? * Your friend sends you a package file, and you have no idea what the package does, what it installs, or where it originally came from. * You know that you installed XFree86 a couple months ago, but you don't know what version, and you can't find any documentation on it. https://www.gratisexam.com/ The list could go on, but you get the idea. The rpm -q command is what you need. If you're the kind of person that doesn't like to have more options than you know what to do with, rpm -q might look imposing. But fear not. Once you have a handle on the basic structure of an RPM query, it'll be a piece of cake. QUESTION 2 On your Oracle Linux 6 system, you have to configure the eth0 network interface to 100 MB/sec, half duplex without trying to autonegotiate. Which command will help you configure this requirement? A. # ifconfig eth0 speed 100 autoneg off duplex half B. # ethtool interface eth0 speed 100 autoneg off duplex half C. # ifconfig interface eth0 speed 100 autoneg off duplex half D. # ethtool –s eth0 speed 100 autoneg off duplex half Correct Answer: D Section: (none) Explanation Explanation/Reference: Explanation: When I have a device that is acting up, I tend to run: ethtool ethX, check the Supported link modes, the Link partner advertised link modes and the actual speed and Duplex. If my Supported link mode is set low (say 10/Half for some reason) but my switch supports 1000baseT/Full then I'll use ethtool -s ethX to change my ethernet settings to 1000baseT/Full. Just about anything you see from: ethtool ethX, can be changed with ethtool -S ethX. In this case you would use the following: ethtool -S eth0 speed 1000 duplex full autoneg on QUESTION 3 DTrace is being ported from Solaris to Oracle Linux. Which three statements are true for the DTrace tool? A. DTrace allows static and dynamic tracing of your applications and your kernel. B. DTrace tool is used to compile debug kernel modules and device drivers C. DTrace allows you to dynamically define probe points on the fly. D. DTrace probes and probe points are usually defined by the user using scripts written in a language called D. E. DTrace tool is based on the strace Linux tool and includes both user and kernel strace features. Correct Answer: ACD Section: (none) Explanation Explanation/Reference: https://www.gratisexam.com/ Explanation: A: DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. C: Key benefits and features of DTrace on Oracle Linux include: / Designed to work on finding performance bottlenecks / (C) Dynamically enables the kernel with a number of probe points, improving ability to service software / Enables maximum resource utilization and application performance / Fast and easy to use, even on complex systems with multiple layers of software D: Testers write tracing programs (also referred to as scripts) using the D programming language (not to be confused with other programming languages named "D"). The language, a subset of C, includes added functions and variables specific to tracing. D programs resemble awk programs in structure; they consist of a list of one or more probes (instrumentation points), and each probe is associated with an action. These probes are comparable to a pointcut in aspect-oriented programming. QUESTION 4 Identify the option with two files that are found in the /etc/sysconfig directory. A. /etc/sysconfig/autofs and/etc/sysconfig/authconfig B. /etc/sysconfig/ifcfg-eth0 and/etc/sysconfig/atd C. /etc/sysconfig/resolv.conf and/etc/sysconfig/network D. /etc/sysconfig/resolv.conf and/etc/sysconfig/grub.conf Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: * The /etc/sysconfig/autofs file defines custom options for the automatic mounting of devices. * The /etc/sysconfig/authconfig file sets the kind of authorization to be used on the host. Note: * /etc/sysconfig/network Used to configure networking options. Incorrect: Not C, Not D: https://www.gratisexam.com/ * The program that resolves hostnames to IP addresses reads a file called resolv.conf. This file is located in /etc/resolv.conf directory. QUESTION 5 Which two options can be completed when using the Firewall Configuration Tool, system – config – firewall? A. Write complex firewall rules for checking, logging, and rejecting inbound and outbound connections B. Enabling or disabling the firewall entirely C. Build a filter to obfuscate sensitive data (national ID numbers, Credit Cards, and so on) D. Select the services that have access to the network resource Correct Answer: BC Section: (none) Explanation Explanation/Reference: Explanation: system-config-firewall The GUI screen to control the firewall is available from the menu (System > Administration > Firewall) or can be started from the command line using the system- config-firewall command. Once started, the toolbar provides buttons to allow the firewall to be enabled/disabled (B). You can also configure basic trusted services, such as SSH, FTP and HTTP (C), by putting a tick in the appropriate checkbox and clicking the "Apply" button on the toolbar. https://www.gratisexam.com/ The "Other Ports" section allows you to open ports that are not covered in the "Trusted Services" section. QUESTION 6 Identify the Oracle-supported source for obtaining Oracle Linux A. From any good Linux distribution B. From Oracle's eDelivery software delivery cloud C. From Oracle Metalink Support D. From Linux vendors such as Red Hat or SUSE E. From Anaconda Installer Correct Answer: B Section: (none) Explanation Explanation/Reference: https://www.gratisexam.com/ Explanation: * Oracle Software Delivery Cloud. Here you can find downloads for the Oracle Linux Operating System, Oracle VM, and Oracle VM Templates for both Linux and Solaris. QUESTION 7 View the output below. As oracle user, you run the following command on your Oracle Linux 6 system: [oracle@dbhost ~ ] $ [oracle@dbhost ~] $ nice - - 10 ./myscript.sh & [1] 2735 [oracle@dbhost ~] $ nice: cannot set niceness: permission denied Why is the nice command failing? A. Shell scripts cannot be assigned a negative nice value. B. There is already another process running with same niceness value on this system. C. A negative nice value can be set by the root user. D. A nice value of -10 is not the permissible niceness range. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: Only a privileged user may run a process with lower niceness: $ nice -n -1 nice nice: cannot set niceness: Permission denied 0 $ sudo nice -n -1 nice -1 Note: Sudo stands for either "substitute user do" or "super user do" (depending upon how you want to look at it). What sudo does is incredibly important and crucial to many Linux distributions. Effectively, sudo allows a user to run a program as another user (most often the root user). QUESTION 8 You have to mount the Oracle Linux ISO image file OracleLinux –R6 – U2 – Server – X86_64-dvd.iso to the /media/cdrom mount point. Which command will help you mount the Oracle Linux ISO image file? A. # mount OracleLinux –R6 –U2 –Server X86_64-dvd.iso /media/cdrom https://www.gratisexam.com/ B. # mount –t DVD OracleLinux –R6 –U2-Server-X86_64-DVD.iso/media/cdrom C. # mount /dvd/OracleLinux -R6 -U2- Server=X86_64-dvd.iso /media/cdrom/OracleLinux-R6-UI-Server-X86_64-dvd.iso D. # mount – 0 ro, loop oracleLinux –R6 –U2 –Server –X86_64 –dvd.iso /media/cdrom Correct Answer: D Section: (none) Explanation Explanation/Reference: Explanation: Mount the DVD iso of the desired update of Oracle Linux Release 5. Use the following command for mounting the DVD media inserted in /dev/cdrom # mount -r -o loop -t iso9660 /dev/cdrom /mnt Use following command to mount iso image file # mount -o loop <iso image file name> /mnt QUESTION 9 You have to find the default runlevel of your Oracle Linux system. Which file will help you find this information? https://www.gratisexam.com/ A. /boot/grub/grub.conf B. /etc/inittab C. /etc/rc.d/rc.sysinit D. /etc/rc.local E. /etc/rc.d/init.d Correct Answer: B Section: (none) Explanation Explanation/Reference: https://www.gratisexam.com/ Explanation: The default run level is specified in the /etc/inittab file. QUESTION 10 Examine the following commands: # groupadd project # mkdir /usr/share/project # chown –R root.project /usr/share/project # qpasswd –a scott project # qpasswd –a foo project # chmod 2775 /usr/share/project Based on the commands, which statement is correct?
